An Algorithm For Plotting Computerized Hidden-Line Perspectives

Canbulat, İbrahim

Within the general classes of communication media, there are those specific ones that will match well defined communication need. The architect must be assured that the alternate costs and flow times are favorable in terms of the total communication value of the medium. Architect's disciplinary communication media are established on graphical symbols such as plans, sections, elevations, perspectives etc. The communication media of computers are entirely different from those of the architects. This communication gap between architects and the computer have a detrimental effect on the use of computers by architects. If a graphical information medium is designed between the architects and the computer the architect will, then best exploit the possibilities of the computer. Perspective drawings are the most favorable graphical instruments for the presentation of the three-dimensional objects. 1 They are helpful to simulate the perceiving of space. The architect can evaluate the spacious quality of his/her design proposal by checking the drawings. He can also use the drawings to present his design to the client or the partners or any other interested group. Besides these usages, the computer can give outputs for some programs as perspective drawings if programmed so. There is a number of computer programs on perspective drawings already prepared. 2 Some of the programs can also be called by other technical programs to transfer output data graphically. In the following paragraphs, the process of defining the three-dimensional objects int o computer, the model of the perspective projection and an outstanding problem of perspective projection which is called hidden-line problem are discussed in detail, and some sample outputs are given. In the last section the program generating the model is described, and the physical characteristics of the program are given.


An Eye Tracking Analysis of Conversational Violations in Dyadic and Collaborative Interaction
Cagiltay, Bengisu; Acartürk, Cengiz (2022-01-01)
Linguistic principles are crucial in maintaining reliable and transparent communication for dyadic interactions. However, violating these principles might result in unwieldy and problematic communications. We use gaze as a medium to explore how visual attention and task performance changes when conversational violations occur. We conducted an eye-tracking study (N = 17) measuring changes in visual patterns in response to social communication errors, specifically Grice's Maxims violations. Our study investig...
An investigation of interactions with conversational violations: Insights from visual perception and Gricean Maxim violations
Çağıltay, Bengisu; Acartürk, Cengiz; Department of Cognitive Sciences (2020-11)
Linguistic principles at various levels are crucial in maintaining a reliable and transparent communication for dyadic interactions. However, violating these principles might result in unwieldy and problematic communications. Gaze can be a medium of reflecting the cognitive responses when conversational violations occur. An eye-tracking study was conducted to investigate visual patterns in communication in response to social communication errors, specifically Grice’s Maxims violations. This study investigat...

A tool for visualizing the communication events in a parallel processing system consisting of transputers is presented. A user program written in OCCAM language is preprocessed by this tool to add run-time event timing mechanisms. Time-stamping data thus obtained is then displayed by a second tool in a graphical format which accurately illustrates any channel or link communication occurring during the execution of the user program. This knowledge enables the user to gain a wider insight in the improvement o...
A statistical unified framework for rank-based multiple classifier decision combination
Saranlı, Afşar (2001-04-01)
This study presents a theoretical investigation of the rank-based multiple classifier decision combination problem, with the aim of providing a unified framework to understand a variety of such systems. The combination of the decisions of more than one classifiers with the aim of improving overall system performance is a concept of general interest in pattern recognition, as a viable alternative to designing a single sophisticated classifier. The problem of combining the classifier decisions in the raw form...
A case-based reasoning model as an organizational learning tool
Ozorhon, B,; Dikmen Toker, İrem; Birgönül, Mustafa Talat (null; 2005-06-03)
Organizational learning (OL) is a set of activities to obtain organizational memory (OM) byacquiring, sharing, interpreting, integrating and institutionalizing knowledge. Although the OLprocess of construction firms has been discussed for several times, utilization of the output ofthese activities has not been investigated in depth. All companies can learn but the advantage oflearning is revealed when companies enhance their decision-making abilities through their OM.The major objective of this...
